P+S HEXAMO Mount for Leitz HEKTOR Cine Primes on ARRI ALEXA

Cinematic look meets mechanical precision. Until now, the new Leitz HEKTOR Cine lenses were developed exclusively for modern mirrorless camera systems.

A major reason for this is the short flange focal distance of the mirrorless platforms they were designed for. Because the HEKTOR lenses were engineered around these short flange depths, using them on the ARRI Alexa was previously impossible. A conventional adapter would position the lens too far from the sensor, making infinity focus unattainable.

P+S Technik now overcomes this limitation with HEXAMO—a specially developed mount system that enables the use of Leitz HEKTOR Cine lenses on the ARRI Alexa platform.

How does the system work?

The original ARRI lens mount can be removed by loosening four screws. The conversion is carried out on both the camera and the lens.

• HEXAMO camera mount: The original Alexa mount block is replaced with a specially developed low-profile mount from P+S Technik, creating the required flange depth for the HEKTOR lenses.
• Lens interface conversion: Each HEKTOR lens receives a precision-machined three-part rear interface assembly. This replaces the original rear mount and forms the dedicated mechanical counterpart to the HEXAMO camera mount. After installation, every lens is precisely calibrated to ensure accurate flange depth and reliable optical performance.
• Precision engineering: The combination of the HEXAMO camera mount and the dedicated rear lens interface enables HEKTOR lenses to operate on the ARRI Alexa with full infinity focus while maintaining complete compatibility with the camera’s internal filter system.
• Secure locking mechanism: The red locking ring provides a rigid, play-free connection between lens and camera, easily withstanding the forces generated by modern wireless follow focus (FIZ) systems on set.

The Result

The unmistakable look of the Leitz HEKTOR series—characterized by smooth focus roll-off, organic rendering, and distinctive flares—can now be combined with the proven ARRI Alexa platform.

For cinematographers, rental houses, and productions, HEXAMO opens the door to a unique combination of the HEKTOR image signature and the reliability of the ARRI Alexa—something that was previously not possible.
